How to change echo to return in shortcode

    Greeting all,

    I am trying to insert custom field with name of “Screenshot” (there are several of them) to the shortcode as below:

    $mykey_values = get_post_custom_values('Screenshot');
  foreach ( $mykey_values as $key => $value ) {
    echo '<img src="'.$value.'" alt="Screenshot" />';
  }

    But when you use echo in shortcode, it will be placed in the wrong position (top of the post). According to WP Codex, you will have to use return and I am wondering how I can change the code above to return all my custom fields with the name of “Screenshot” to the shortcode. Thank you very much.

    for example:

    $mykey_values = get_post_custom_values('Screenshot');
$output = '';
  foreach ( $mykey_values as $key => $value ) {
    $output .= '<img src="'.$value.'" alt="Screenshot" />';
return $output;
  }

    (untested)

    Does not seem to work but anyway, I think I found a way to implement it using conditional get_post_custom_values to output all the necessary custom fields. Thank you very much anyway!
